This invention relates to roller bearings,

and more particularly to that type of roller bearings commonly known to the trade as the Tlznken bea'ing and generally. used in connection with axles and other vehicle elements. in. this and other types oi roller bearings, for imitancc straight or cylindricalrollers, numerous tedious ()Pfll'tllilOIlS are news sary to accurately and properly assemble the rollers of the bearing, and it is the principal object of this invention to eliminate operations requiring skill and careiulness by providing a roller bearing with rollers that can be expeditiously and common ally assembled, insuring accurate alineinent, proper spacing and precluding any danger of jamming and breaking when subjected to an excessive load.

Another object of my invention is to provide-a taper or conical roller bearing possess ing considerable load carrying ability, the rollers of the bearing being disposed to in sure a uniform distribution of a load and atfo'rd end thrust bearings for any longitudinal movement ot'the load sustaining rollers A further object of my invention is to provide a bearing embodying a bearing cone, conical rollers, a cage, and an outer bearing Incinber or collar, said bearing cone and collar being adjustable whereby either may be shifted to compensate for wear of the conical rollers.

The above are a few of the objects attained by using my improved bearing, and reference will now be had to the drawings, wherein-- Figure l is a cross sectional "iew of the preferred. form roller bearing; Fig. 2 is a longitudinal sectional View of the some; Fig. 3 is a longitudinal sectional view of a ortion of a roller bearing" having a detach able abutment and detachable retaining ring; Fig. 1 iso similar view of a bearing having a permanent abutment and retaining ring; Fig. is similar view of a bearing having a patina ent abutment and a detachable retainin ring in connection with cylin Fig. 11 is a similar view of shearing ShOWlIlg another arrangement of a movable abutment;

trating the manner of assembling rollers and applying the same tobearing cone; Fig. 13 is an elevation of a detached retaining ring; Fig. 14: is a longitudinal sectional view of a portion ot a bearing, showing neck rollers; .iig. l5 is av longitudinal sectional view of the same type of bearing illustrating the hammer of assembling the neck rollers; Figs. l'T-and 18 are elevations of aretaining ring used in connection with the bearing illustrated in Fig. 15, and Fig. 19 is a longitudinal sectional view of a bearing, showing the use of an assembling member for cylin drical or straight rollers.

In describing my invention by aid of the views above referred to, l desire to point out that the same are merely illustrative of examples whercbv my invention may be applied in practice, auell do not care to confine myself to the prevf-e construction and arrangement of parts shown. The following description is therefore to be broadly construed as including substitute constructions and arrangement of parts which are the obvious equivalent of those to be hereinafter referred to. v

'll'iroughoiit the drawings, the reference numeral 1, generally denotes a bearing cone having a concentric opening '2 for an axle or other member (not shown). The bearing cone '1 has the periphery tapering from one end of the cone to the opposite end thereof, and reference will now be had to Figs. 1, 2, 8 and 9 showing the preferred form of construction.

The bearing cone 1 hasthe large end thereof provided with a permanent abutment or flange 3 presenting an annular b'evr elecl shoulder 2 engaged by the beveled laige ends of a plurality of conical rollers 6 spaced upon thetapering peripher of the bearing cone. To maintain the conical roll ers 6 in spaced 'elation updn the bearing '1 a conical cage 7 Is employed andto prevent accidental displacement of the rollers and Q inserts brass or such material that can be stamped 0r pressed, by one or two operations, to form a shell having longitudinal equally spaced openings 9, each of less area than the longitudinal sectional area of a conicil roller, whereby when the rollers are assembled in the cage, preparatory to placing the bearing cone in the cage, the rollers cannot ass through the openings 9, but simply rest m the cage with a portion of each roller protruding through the openings of the cage. To assemble the conical rollers the small end of the cage 7 is held in a hori- Figs. 10 and 1-1. In 10, the anti-frictional balls 21 engage necks 529 of conical rollers 23, and said anti-frictional bulls are arranged in a race at the large end of the bearing. in Fig. 11, the. nti-frictional halls 21 are dis weed between flat ends of rollers ffand a ange 2% on. the bearing cone.

Fig. 5 illustrates cooperatingcylindrical bearing members 27 and 28, a permanent abutment 29. a detachable retaining ring 30, cylindrical or straight rollers 31. and n cylindrical cage 32, all oi. these elements being easily assembled and/the rollers 31 having practically the c load carrying ability as the co I I rgi i rixl to Fig. ll it vqili he observed that a zontal plane and the conical rollers placed core i0 f :ilitatcs assembling the cylindrical in the openings 9 of the cage. the P0115315 resting in said opening by reason of the Walls of the cage slanting away from or being disposed at an angle -relative to the vertical axis of the cage when held in an upright position. Consiilcrablc importance is attached to this manner of assembling the rollers in the cage as the operation can be expeditiously performed. A. bearing cone can then be placed in the cage with the pc riphery of the bearing engaging the pcriphery of the conica rollers. The retaining ring 8 can then be placed in position and the rollers are held relative to the bearing cone whereby the same can be handled as a unit and placed in an outer bearing member or collar 10. which has a tapering annular bearing surface 11 engaging the rollers 6.

As shown in Figs. 1, 2 and 3, the small end of the bearing cone 1 has an annular groove 12x50 receive the retaining ring 8. said rin being split to facilitate its instal lation. --.[l1iS retaining ring is simply em ployed to prevent accidental displacement of the rollers and does not receive any end thrust of the rollers when the bearing is in use.

As shown in Fig. 4. the retaining ring can be pressed on or otherwise secured to the bearing cone 1, the ring in this instance be ing designated l3 andffitting snugly upon the periphery of the bearing cone.

As shown in Figs. 6 and '7 the ring may be in the form of a. cap lei provided with a.

central opening 16 registering with the opening 2 of the bearing cone. The cap has dove-tailed grooves 1.7 adapted to receive dove-tail tongues 18 carried by the small end of the bearing cone. This construction permits of the retaining ring being ea i y and quickly removed it occasion so requires.

In Fig. 3 there is illustrated a detachable abutment 19 in the form of a ring fitted in a groove 20 provided therefor in the large end of the bearing cone, and in some instances I can use a movable abutment in the fonfiof anti-frictional balls 21, as shown in rollers and that a bearing cone follows the core. thus preventing displacement of the cylindrical rollers, which are spaced by the cylindrical cage 32;.

Fig. i2 clearly indicates the manner of assembling the conical rollers preparatory to placing the some in engagement with. u hear in? cone. and it is to be noted that the conicai roll-c 3 are approxi'znately the length of the bearing cone. in other Words, there is one cage for. each hearing cone and the size and; shape o'E-thc conical rollers are conducive to rapid assembling in a. cage. it is an extremely easy matter to place the hearing cone in the cage to rest upon the rollers, and then spring the ret: hing ring into position to hold the cage relative to the bearing cone, thus permitting of the some being handled as a unit and sli "ed into an outer hearing member or col This cannot be accomplished on a :ouut of the construction of a great many roller hcarin' 's. consequently I am able to materially reduce the working! force and expense hretdforc necessary for assembling the part: of roller he... ng. I am aware cages have heretofore been used in hearings, but in every. instance the pro. duction of the cage re :d. a multiplicity of operations on account o mtaiuirig flanges,

' etc, whereas no}; improved cage can be produced by one or two operations.

A. further modification of myinvcntion is illu trated in to 18 inclusive. Eli/OW- ing a hearing cone. wherein conical rollers 33 have he smell cm. rovideil with annular groo' 34.- iorn' g :s and adapted to gage in the grooves m, said rollers is a retaining ring After the rollers are assembled in acage, the retaining ring, which islcai r0 l'clh prcrioausly described. By-

In Fig. 19 there is shown an assei'n'bling member ell) having a groove all for a cylindricalor straight cage 42 adanted to receive rollers 43. llhe rollersare held in position by a resilient ring ll forming part of the member 40, and said member gives Way to a bearing cone 45 which is slipped into position.

What I claim is z- 1. A roller bearing comprising a bearingcone, said bearing-cone having the small end thereof provided with an annular groove, a plurality of rollers on said bearing-cone and having ends thereof provided with annular grooves, and a retaining ring adapted to be distended to engage in the grooves of the rollers and then released to engage in the grooves of said bearing-cone.

2. A roller-bearing comprising a bearingcone having the large end thereof provided with an annular abutment and the small end thereof With an annular groove, conical rollers on said bearing-cone having ends thereof engaging the abutgientof said bear ing-cone and ends thereofprovided with annular grooves, a cage spacing said conieal rollers on said bearing cone, and a retaining ring adapted to be distended to engage in the grooves of said conical rollers whereby said bearing-cone can be placed in positioin said retaining ring when released engaging in the groove of said cone to cooperate with the annular abutment thereof in preventing longitudinal displacement of said conical rollers.

3. In a roller bearing, a cage rollers in said cage, a bearing cone, and means adapted to hold said rollers in said cage until said bearing cone is placed in engagement with said rollers and engage said bearing cone to maintain said bearing'cone Within said cage.

4. A roller bearingicomprising a hearing member, said bearing member having an end thereof provided with an annular groove, a plurality ofrollers on said hearing member and having ends thereof provided. with annular grooves,.and aretaining ring adapted to be distended to engage in the grooves of the rollers. and then released to engage in g the groove of said bearing member.

In testimony whereof I affix my signature in presence of two witnesses.
